Normally Open Load Operation: Switch closure to terminals 5 and 7 turns programmable Relay "on" and energises load. Same switch opening will turn "off" programmable Relay and de-energise load. Terminals 6 and 8 are not used.
Normally Closed Load Operation: Switch closure to terminals 6 and 7 turns Programmable Relay "off" and de-energised load. Same switch opening will turn "on" programmable Relay and energise load. Jumper must be connected between terminals 5 and 7... terminal 8 is not used.
Latching "A" Operation: For refill control, momentary switch closure to terminals 5 and 7 turns Programmable Relay "on" and energised load. Load remains "on" until the Programmable Relay turns "off" with a momentary switch closure at terminals 6 and 7. The load is then de-energised. Jumper must be connected between terminals 7 and 8. For pump-down, reverse wires on terminals 5 and 6.
Latching "B" Operation: Momentary switch closure to terminals 5 and 7 turns Programmable Relay "on" and energises load. Load remains "on" until the N.C. switch terminals 7 and 8 opens. The Programmable Relay turns "off" and load is de-energised. Terminal 6 and jumper are not used.
Note: Latching function should be accomplished on sensor input side of the Programmable SAFE-PAK®. No latching function is advised on the output power circuit side.
